e u NPQWDERQ SPECIFICATION forming part of Letters Patent No. 418,635, dated December'31, 1889.

Application filefi April 22, 1889. Serial No. 308,143. (No specimens.)

To all whom it may concern."

Be it known that I, ARSEN F. WooDs, of Lagro, in the county of \Vabash and Stateof Indiana, have invented certain new and 5 useful Improvements in Gunpowder; and I do hereby declare that the following is a full, clear, and exact descriptionof the invention, which will enable others skilled in the art to which it appertains to make and use the My invention relates to an improvement in gunpowder, and it consists in a new and peculiar compound forming "an explosive possessing great advantages over the explosives [5 of this class heretofore in use-that is, possessing great strength witha minimum recoil, exceedingly cheap, andeasy to manufacture,

"requiring no dry house in process of manufacture, there is no danger in manufacturing 20 the same, possesses great advantages for use in sporting-guns, rifles, &c'., as it generates but little smoke, leaves no smell, and leaves the gun dry and requires but very little cleaning after its use.

This compound consists of the following ingredients, in about the proportions named, to wit: chlorate of potash, two parts; prussiate of potash, one-half of one part; sugar, (granulated) one-half of one part; or the pro 0 portions might be as follows, to wit: chlorate of potash, four parts; prussiate of potash, one part; sugar, (granulatcd,) one part.

In manufacturing the ingredients they are separately ground and then mixed as any powdered compound is mixed, The prussiate 3 5 of potash is preferably the yellow variety, andas this substance is a nori-explosiveit reduces the excessive force and power of the chlorate of potash, which is too great an explosive to be used alone. The-sugar is in-. ;c tended to-moisten the compound and dissolve particles that otherwise would remain unburned when the explosion takes place, and,-

further, thesugar makes the compound less infiammableand slower in burning, but has a 5' power and spirit that adds to the compound.

What I claim 'i s r 1. An explosive in powdered form containing as ingredients chlorate of potash, yellow potash, and acarbohydrate, such 50 ence of two witnesses.
